I'm still kind of new to violin. I play, a lot, and took lessons for a while. I'm nowhere good enough to just pick this piece of music up and start playing. But I can say that I'm very good at repeating something over and over for months till I'm good at it. Now when i picked up this piece of music and poked around at it, I realized that I'm almost dead sure when I see/hear people play it, they start generally around 5 position, give or take. But my sheet music is shown starting in first position, and doesn't show any position changes. So I'm guessing that there is a change in key that I'm missing. I would very much appreciate it if someone could point out position changes, change in key, or whatever it is I need for it to work out right. Along with this post I'll be posting scans of my sheet music, and a video of the performance.

This is a pretty good view of someone performing it: http://www.youtube.com/watch?v=MnL3KlNZUog

Here is my scan, of just the violin section of the piece. I have a full piece also if it's needed:

The 2 under the b-flat is second finger on the A string, which would be seventh position. the numbers under/over the notes say which finger goes to it. the numbers usually only show up when there is a position change or there is a certain fingering the composer wants. Roman numerals indicate which position is to be played, but none show up here.

Okay, that is wrong. Don't listen to that.
The two under the first b-flat refers to second finger on the E string- in other words, third position. You play 2 on E, 4-1 on A, 3-1 on E (ignore that four under the A), 1 on A, 4 on E, 3-1 on A, 2 on E, 4 on A, 2 on E, and then shift up to sixth position, and slide down with the descending notes. I know this seems a bit complicated, but in other words- stay in third position for the first two and a half measures.
If you're having this much trouble with it, you should really consult a teacher.This isn't the kind of piece you can fake.
